This review finds that laparoscopic surgery for small bowel Crohn's disease may be as safe as conventional surgery. There is no significant difference in the perioperative outcomes and long-term disease recurrence rates. However, there are only two RCTs (including 120 patients) so far and no reliable conclusions can be made regarding the benefits of laparoscopic surgery.

Wprowadzenie
Crohn's disease (CD) is a chronic inflammatory bowel disease that most commonly involves the terminal ileum and colon (55 percent). Surgical treatment is required in approximately 70 percent of patients. Multiple procedures and repeat operations are required in 30 - 70 percent of all patients (Duepree 2002) but the disease remains incurable.
Laparoscopy has gained wide acceptance in gastrointestinal surgery with potential advantages of faster return to normal activity and diet, reduced hospital stay, reduced postoperative pain, better cosmesis (Duepree 2002, Dunker 1998, Milsom 2001, Reissman 1996), improved social and sexual interaction (Albaz 2000) and its use is accepted in benign and malignant colorectal diseases. Laparoscopic surgery offers additional advantage of smaller abdominal fascial wounds, low incidence of hernias, and decreased rate of adhesive small-bowel obstruction (Albaz 2000) compared with conventional surgery reducing the need for non-disease-related surgical procedures in CD population.
There are concerns about missing occult segments of disease and critical proximal strictures due to limited tactile ability, earlier recurrence due to possible reduced immune response induced by laparoscopy, technical difficulty due to fragile inflamed bowel and mesentery and the existence of adhesions, fistulas, and abscesses (Uchikoshi 2004). It is therefore important to evaluate the potential benefits and risks of laparoscopic surgery versus open surgery in patients with small bowel CD (Lowney 2005).
Cele
To determine if there is a difference in the perioperative outcomes and re-operation rates for disease recurrence following laparoscopic surgery compared to open surgery in small bowel CD.

Kryteria doboru badań
Randomised controlled trials (RCT) comparing laparoscopic and open surgery for small bowel CD were included.
Zbieranie i analiza danych
Two reviewers independently assessed the studies and extracted data. RevMan 5.0 was used for statistical analysis.
Główne wyniki
Two RCTs comparing laparoscopic and open surgery for small bowel CD were identified. Long term outcomes of the patients in both the trials were published separately and these were included in the review.
Laparoscopic surgery appeared to be associated with reduced number of wound infections (1/61 vs 9/59), reoperation rates for non disease related complications (3/57 vs 7/54 ) but the difference was not statistically significant [p values were 0.23 and 0.19 respectively]. There was no statistically significant difference between any of the compared outcomes between laparoscopic and open surgery in the management of small bowel CD.
Wnioski autorów
Laparoscopic surgery for small bowel CD may be as safe as the open operation. There was no significant difference in the perioperative outcomes and the long term reoperation rates for disease-related or non-disease related complications of CD.
